Abstract (en)
[origin: WO2012040756A1] For a valve having a pressure limiting function for common-rail heavy oil injection systems for internal combustion engines, comprising a valve carrier (18), a valve piston (21), which is movably supported in the valve carrier (18) and which interacts with a valve seat (22) while the valve is closed, and a compression spring (24) that applies a compressive force acting in the closing direction to the valve piston (21), a pin (30) that acts on the valve piston (21) in the closing direction is arranged in such a way that the pin can be moved with the aid of an actuating element against the compressive force of the compression spring (24) in order to open the valve in a controlled manner in order to develop a flushing function.
